    Abstract

    High switching frequencies(>1 MHz) become available due to the development of wide bandgap semiconductors. This trend of increasing operating frequency in power electronics results in the reduction of output filter sizes and costs. As frequency increases, parasitic behavior of components become more dominant. This paper shows the possibility to shift the generated EMI peaks to the most effective bandwidth of a COTS filter by reprogramming the FPGA based sPWM generator. The peak EMI output is therefor reduced by means of a mere firmware update. While possible, spread spectrum has not been addressed in this paper, due to the lack of effect it has on the peak emissions.
